PLANER AND ATTACHMENT THEREFOR.

Specification of Letters Patent. Patented Mar. 11, 1919.

Application led June 13, 1917. Serial No. 174,517.

necessary either lto provide an excessively long tool or to provide a special toolv slide adapted to project into the recess. Each of these methods is of limited utility and each of them is open to it subjects the tool heads and the cross rail to abnormal turning or twisting stresses for which they were not intended.

The principal object of the invention is to provide a planer or an attachment therefor which is adapted for planing surfaces which are located in deep recesses. In accordance with my invention, planing can be eEected in very deep recesses and can be done without subjecting the tool heads and cross rail to any undue or abnormal stresses'.

In the accompanying drawings I have shown one embodiment of the invention, but it will beunderstood that the drawings are for illustrative purposes only Vand are not intended todene or limit the scope of the invention, the accompanying claims being relied upon for that purpose.

Of thedrawings:

Figure 1 is a side view of a planer embodying the invention.

Fig. 2 is a front view.

Fig. 3 is a partial plan view.

Fig. 4 is a detail view showing the means for holding the toolbar.

Fig. 5 is a detail view showing the lower end of the tool bar.

Fig. 6 is a detail view showing the devices for connecting the tool with the tool bar.

In the drawings I have illustrated somewhat fully many of the principal elements of a planer, but it will be understood that the serious objection that adapted to most of these elements are well known and do not by themselves constitute any part of this invention.

As illustrated, the planer comprises a bed 1 upon which is mounted areciprocating table 2. TheV table is driven in any usual or preferred manner, as, for instance, by means of the belt pulleys 3 and 4 which are connected with the table through any suitable gearing. For reversing the movement of the table there is provided a belt shifter 5 which is operated by dogs 6 and 7 carried by the table. At the sides of the bed are suitable uprights or housings 8 and 9 which are connected by an arch 10. Vertically adjustable along suitable ways on the uprights is a cross rail 11. This rail can be moved vertically by means of screws 12, 12 which are suitably connected to receive power from a belt wheel 13.

`Mounted on the cross rail 11 are one or more tool heads, and in the drawings two tool heads are illustrated. Each tool head comprises a saddle 15 which is horizontally movable along ways formed on the cross rail. Angularly adjustable on the saddle is a swivel plate 16 and adjustable along ways formed on the swivel plateis a slide 17 adapted to be controlled by a screw 18. Angularly adjustable on the slide 17 is a plate 19 adapted to be secured in adjusted position by means of bolts 20, and horizontally pivoted to the plate 19 is an apron 21 carry the cutting tool. For moving either or both of the tool heads horizontally along the rail in either provided with a keyway throughout, and

which is adapted to turn the screw 18 by means of suitable `gearing not shown. The

construction is such that the power connec tion with the screw 18 is maintained for all angular positions of the slide and swivel plate. For turning any or all of the said shafts 22, 23- and 24, there is provided a vheld in' an upright position but can be ad- Vjusted angularly Vin accordance with the.y

vment of the tools.

suitable feed mechanism 25 which is illustrated in part in Figs. l and 2 and which receives Vits power from.` the main drive mechanism. This feed mechanism need not be described in detail, and it will be suicient to point out that itwserves upon each movement of the table 2 to turn one or more of the said horizontal shafts through a definite angle toV effect the required move- Referring now tothoseparts of the construction to which my invention more paryticularly relates, 26 represents a tool-,carrying barwhichis4 adapted to be connected to the apron 21 in place of thewusualtool. Preferably, in order that the bar may be securely connected to the apron, I provide a special clip 27 for holding it, this clip being adapted to be held by bolts 28 which' enter the usual T-slots with which the apron is provided. By means offthe clip the bar-is angular adjustment of the slideV 17 and plate-19.

' Atv the lower end of thebar 26, means are provided for holding aV cutting tool. As

' illustrated, there is a plate 29 which is provided with a pivot boss 30 which extends through an aperture inthe bar. The boss is threaded at its rear end to receive-a nut `3l which, when tightened, clamps the plate 29 Horizontally pivoted to the' in n position. plate 29 Vis an apron 32 which carries bolts and clips wherebyv theA cutting tool 33 is secured. Y l

Extending across the planer from one housing to the other is a supplemental rail 34 which is lpositioned to contact with the front'fa'ce of the Vbar 26. This rail is positioned at a Vrelatively'high elevation and-is held in place by any suitable means such as the'brackets 35, 35 which Iare connected with fthe uprights.

As clearly shown in Fig. 2, theY barf26permits the cutting tool-33 to Vbe positioned in a recess at a point which could not be reached by a planer-as ordinarily constructed. The

Y pivotal mounting of the plate 29 permits the :soV

Y required, and the ybackward movement of the work. 26 can be. adjusted in any lof theways inV whichV the cutting Atool is `usually adjusted. That is,YV the-bar can be moved upward or YdownwardV inthe clip 27 and can be secured in adjusted position; angulariadjustment canV be'eii'ecte'd .byV means of the plate 19 or toolV to be turned to one side or the other as pivoting of the vapron 32 permits the'tool fto Vbe relieved The bar the swivel plate 16; and the bar can be moved vertically or angularlyf or horizon-V Ytally either preliminarily or duringV opera-1V tion byimeans'oftheifeed mechanism.

The cross rail'34s'erves to support the bar 26 and prevents .the reaction resulting from j adapted to be excessV stress.

during the the cutting from being transmitted to the cross rail in the form of a twisting stress thereon. rlhe rail 34, while fully supporting the bar in the way described, nevertheless leaves it free to be adjustedeither Vvertically or horizontally or va'ngularly as required.
